Python 风格指南 | 未完待续

一个典型模块的内部结构：

起始行
模块文档(文档字符串)
模块导入
(全局)变量定义
类定义(若有)
函数定义(若有)
主程序

样例代码：

#!/usr/bin/env python
#coding:utf-8

"this is a test module"

import sys
import os

debug = True

class FooClass(object):
    "Foo class"
    pass

def test():
    "test function"
    foo = FooClass()
    if debug:
        print 'ram test()'

if __name__ == '__main__':
    test()

#!/usr/bin/env python

#coding:utf-8

"this is a test module"

import sys

import os

debug = True

class FooClass(object):

"Foo class"

pass

def test():

"test function"

foo = FooClass()

if debug:

print 'ram test()'

if __name__ == '__main__':

test()
